That's an incredibly large amount per user? I have worked on a couple online dating sites, including one that was fairly popular (Let's Date - which stiffed me for my last invoice before they went belly up grrr). Unless you're storing images in the database, it's really hard to generate 600k for a dating workload - even with indexes.
The only thing I can imagine generating 600k per user is putting something like "hit tracking" in the database. Which I've done - yes it adds up - but it's also relatively easy to move to some other kind of store.
